我对 Rails 完全陌生，在让我的嵌套资源/模型工作时遇到了很多麻烦。每当我尝试提交表单时，都会遇到路由错误。

No route matches {:action=>"show", :controller=>"tests", :test_suite_id=>#<Test id: 8, name: "1", test_type: "1", result_type: "1", input: "1", created_at: "2012-06-29 07:01:11", updated_at: "2012-06-29 07:01:11", date: "1", test_suite_id: 4>}

有人可以向我解释为什么在异常输出中出现太多 test_suite_id 以及为什么操作是“show”而不是“index”？当我提交表单时，我想回到索引 /test_suites/:test_suite_id/tests。

以下是所有相关代码：

路线.rb

  resources :test_suites do
    resources :tests
  end

测试控制器.rb

class TestsController < ApplicationController
    # GET /tests
    # GET /tests.json
    def index

        @testsuite = TestSuite.find(params[:test_suite_id])
        @tests = @testsuite.tests

        respond_to do |format|
            format.html # index.html.erb
            format.json { render json: @tests }
        end
    end

    # GET /tests/1
    # GET /tests/1.json
    def show
        @testsuite = TestSuite.find(params[:test_suite_id])
        @test = @testsuite.tests.find(params[:id])

        respond_to do |format|
            format.html # show.html.erb
            format.json { render json: @test }
        end
    end

    # GET /tests/new
    # GET /tests/new.json
    def new
        @testsuite = TestSuite.find(params[:test_suite_id])
        @test = @testsuite.tests.build

        #@test = Test.new
        @test.build_hardware
        @test.build_software

        respond_to do |format|
            format.html # new.html.erb
            format.json { render json: @test }
        end
    end

    # GET /tests/1/edit
    def edit
        @test = Test.find(params[:id])
    end

    # POST /tests
    # POST /tests.json
    def create

        @testsuite = TestSuite.find(params[:test_suite_id])
        @test = @testsuite.tests.build(params[:test])

        respond_to do |format|
            if @test.save
                flash[:notice] = "Test Added Succesfully"
                format.html { redirect_to [:test_suite, @test], notice: 'Test was successfully created.' }
                format.json { render json: @test, status: :created, location: @test }
                else
                format.html { render action: "new" }
                format.json { render json: @test.errors, status: :unprocessable_entity }
            end
        end
    end
end

_form.html.erb

<%= form_for([:test_suite, @test], :action => "index") do |f| %>
  <% if @test.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@test.errors.count, "error") %> prohibited this test from being saved:</h2>

      <ul>
      <% @test.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>
  <br />
  <h2>Test information</h2>

  <div class="field">

  <div class="field">

    <% end %>
  </div>


  <div class="actions">

该错误是由这两行的不一致引起的：

resources :test_suites do

<%= form_for([:test_suite, @test], :action => "index") do |f| %>

resources（相对于）的使用resource意味着一个集合（相对于单一资源）。嵌套在其中的资源不属于集合，但它们必须属于集合中的特定成员。

在你的form_for([:test_suite, @test])你说你想要一个属于名为“test_suite”的单一资源的表单。

您要么需要将父资源更改为单数，要么传入特定test_suite实例（即：）form_for([@a_test_suite_instance, @test])。
